PRESSI SPECIFICATION forming part of Letters Patent No. 294,571, datedMarch 4-, 18.84.

- Application filed December 12,1883.' (N0 model.)

To all whom it may concern.-

Be it known that I, GEORGE E. BOOMER, a

citizen of the United States, residing atTarrytown, inthe county ofWVestchester and State of New York, have invented new and usefulImprovements in Presses, of which the following is a specification.

The object of my invention is to furnish a press in which a series ofplates, each filled with the proper material, may be laid one upon theother, to be compressed in an upward direction; and it consists in, themeans herein vation thereof.

after described, for loading and unloading the press and for keeping thepress-plates in a true vertical lane.

In the accompanying drawings, Figure 1 shows a press in verticallongitudinal section embodying my invention. Fig. 2 is aside ele- Fig. 3is-a cross-section of the same. Fig. 4 is a horizontal section on thelinea: .r, Fig. 1.

Similar letters indicate corresponding parts.

The letter A designates the head-block of the press, rigidly supportedby posts B or other suitable means. Through this headblock extend screwsGin this example four in nun1berwhich also pass through the bed' orfollower E, andthrough nuts F thereof, so that if a revolving motionisimparted to either the screws or the nuts the follower is raised orlowered, as the case maybe, by that means. In the present example of myinvention the nuts F are fixed to the follower E, to remain stationary,and the screws 0 are geared toterial to be pressed.

gether and to a driving-shaft, O, to receive a revolving motionsimultaneously in like directions, they being stepped at thelower endsin blocks D. Y

On the head-block A, or on any other suitable part of the press, arearranged two movable ledges, G, the office of which is to tem-. porarilysupport, at a point above the follower E, the plates or racks 0,containing the ma In their normal positions these ledges G are paralleland opposite to each other in a horizontal plane, as shown in Fig. 1, sothat the press-plates 0 may be conveniently slid thereon from one end,and when either of the plates has been properly adjusted 011 theledgesthe latter are in-prae tice displaced simultaneously, so as todeposit the plate on thefollower, by the following means: Each of theledges is supported by a bracket, G, which is hinged to the head-blockby a pivot, G, on one end of which'is an arm supportingbrackets areswung away from each other, thereby displacing the ledges, while whenthe parts are released the ledges return to a normal position bygravity, they remaining in that position until again displaced. Forconvenience of operation, one of the levers-in this example one of thebracket-1e vers H-is provided with a handle, H 7

On one side of the press is a platform, I,

which serves to receive and support the press plates H while they arebeing filled or emptied, this platform being substantially in thehorizontal plane of theledges G, and being supported by brackets Korother suitable, means. From the outer edge of the platform I extend, onan inclined plane to the ground .or any other proper place, rails J, topermit the press-plates O to be conveniently elevated to or lowered fromthe platform, these rails being also extended along the platform tofacilitate the movement of the plates thereon to or from the press. Thepress-plates, which are deposited 011 the follower E by or from theledges G, are received in vertical ways N, and thereby guided in theup-and-down movement of the follower to preserve atrue vertical plane,these ways being located at the corners of the press-plates, and beingunited at the upper ends to the head-block, or any other suitable partof the press-structure.

The following is a brief description of the method of working the press.lower E is raised to within ashort distance of the ledges G. Apress-plate is brought up on the platform I and the plate is filled withthe proper material, as with bags containing lard. The filled plate isthen slid into the The bed or fol press on the ledges G, and when it hasreached the proper position to enter the guideways N the ledges aredisplaced to deposit the plate on the follower. The screwsO are thenstarted to lower the follower at a speed that will suffice to clear aspace for the next plate by the time it can be filled. Each successiveplate is filled and deposited 011 the preceding one until the followerhas reached the lower limit of its movement and the press is entirelyloaded, when the motion of the screws is reversed to raise the followerand properly compress the material. When the press is to be unloaded,the material is relieved from pressure and the top plate, with its lead,is drawn out on the platform 1. The follower E is then made to rise,andthe plates are withdrawn as fast as they reach the level of the table I,until the follower has been entirely emptied, when it is stopped, itbeingthen in the proper position to be reloaded.

It should be understood that, instead of the screws C and concomitants,any other suitable medium maybe employed for raising and l0wering thefollower.

\Vhat I claim as new,and desire to secure by Letters Patent, is-

1. The combinatiomwith the movable ledges,

arranged opposite each other, for supporting the press-plates, ofdevices connecting the said ledges together and positivelymoving themsimultaneously from the press-plates, to permit the latter to descend,substantially as described.

2. The combination, substantially as hereinbefore set forth, of themovable ledges for temporarily supporting the press-plates at a pointabove the follower, the hinged brackets supporting the ledges, theoperating-levers of the brackets, and the intermediate lever and rodsconnecting such operating levers together.

3. The combination, substantially as hereinbefore set forth, oftheplatform arranged 011 the side of thepress to receive thepress-plates, and the inclined rails leading from such platform.

4-. The combination, substantially as hereinbefore set forth, of themovable ledges for temporarily supporting the press-plates at a pointabove the follower, and the platform arranged on one side of the press,substantially in the horizontal plane of the ledges,to receive thepress-plates, which are to be placed on the ledges, or which are removedtherefrom.

The combination, substantially as hereinbefore set forth, of the movableledges for temporarily supporting the press-plates at a point. above thefollower, and the vertical ways adapted to receive and guide thepress-plates deposited on the follower by the ledges.

In testimony whereof I have hereunto set my hand and seal inthe-presence of two subscribing witnesses.
